MY advice to you is only my personal experience:
There's no need to transfer to a T2 or T3 unless it will get you a better job in the geography you want.
However, your LSAT and grades seem good enough for a lower tier 1 ANYWAY, so I say go for that.
I am at a tier 1, between 25-50 with a relatively "national" name and have had no problem with getting serious leads for a 1L firm job. However, I am an IP person so my experience might be different.
Point being, transfer as high as you can go. Dont just transfer to a T2 or T3 unless its a significantly better school in your geography (i.e. something like going from washburn to KU law)
